Outlook:Selecting an email, extract information from it

Hi, I'm new to programming in Outlook. I've searched quite a few places to find out how to do this.

I want to be able to retrieve information such as the name of the sender, the email body, etc. by selecting an email, then click on a button that I've created. I'm not sure how to refer to the selected email as well as referring to the specific fields of it. I would really appreciate if someone can point me in the right direction.

Thanks in advance.

I have several Outlook code examples on these Forums. ;)

You will want to start with telling us how you added your "button"? Is it added in via an Add-In, Outlook VBA, VB6 automation, or VB.NET/C#, etc.

An email is an Outlook.MailItem. ;)

hey RobDog, thanks for the quick reply :)

I used Visual Studio VB to add the add-in. I found some code, can't remember where now, that adds a button and it's as follow:

VB Code:

Public Sub OnStartupComplete(ByRef custom As System.Array) Implements Extensibility.IDTExtensibility2.OnStartupComplete
 
        Dim oCommandBars As CommandBars
        Dim oStandardBar As CommandBar
 
        On Error Resume Next
        ' Set up a custom button on the "Standard" command bar.
        oCommandBars = applicationObject.CommandBars
        If oCommandBars Is Nothing Then
            ' Outlook has the CommandBars collection on the Explorer object.
            oCommandBars = applicationObject.ActiveExplorer.CommandBars
        End If
 
        oStandardBar = oCommandBars.Item("Standard")
        If oStandardBar Is Nothing Then
            ' Access names its main toolbar Database.
 
            oStandardBar = oCommandBars.Item("Database")
 
        End If
 
        ' In case the button was not deleted, use the exiting one.
        MyButton = oStandardBar.Controls.Item("New Opportunity")
        If MyButton Is Nothing Then
 
            MyButton = oStandardBar.Controls.Add(1)
            With MyButton
                .Caption = "New Opportunity"
                .Style = MsoButtonStyle.msoButtonCaption
 
                ' The following items are optional, but recommended.
                ' The Tag property lets you quickly find the control
                ' and helps MSO keep track of it when more than
                ' one application window is visible. The property is required
                ' by some Office applications and should be provided.
 
                .Tag = "New Opportunity"
 
                ' The OnAction property is optional but recommended.
                ' It should be set to the ProgID of the add-in, so that if
                ' the add-in is not loaded when a user clicks the button,
                ' MSO loads the add-in automatically and then raises
                ' the Click event for the add-in to handle.
 
                .OnAction = "!<MyCOMAddin.Connect>"
 
                .Visible = True
            End With
        End If
 
        ' Display a simple message to show which application you started in.
        'MsgBox("Started in " & applicationObject.Name & ".")
 
 
        oStandardBar = Nothing
        oCommandBars = Nothing
 
 
    End Sub

Also, I've found a function that returns the sender's address. But it takes an Outlook.Mailitem as an input. How can I pass the mail that's been selected by the user?

VB Code:

Function GetMailItemSenderAddress(ByVal oOutlookMail As Outlook.MailItem) As String
        Dim oMapiMessage As Object      'MAPI.Message
        Dim oSession As Object          'MAPI.Session
        Dim sEntryID As String
        '      Dim sEntryID As String
 
        MsgBox(oOutlookMail)
 
        oSession = CreateObject("MAPI.Session")
        'Logon to the existing session
        oSession.Logon("", "", False, False)
        'Get the message Information
        sEntryID = oOutlookMail.EntryID
        sEntryID = oOutlookMail.Parent.StoreID
        'Get the message
        oMapiMessage = oSession.GetMessage(sEntryID, sEntryID)
        'Extract the Sender's Address and Return value
        GetMailItemSenderAddress = oMapiMessage.Sender.Address
 
        oSession.Logoff()
        oSession = Nothing
        oMapiMessage = Nothing
 
        Exit Function
 
ErrFailed:
        ' Debug.Print(Err.Description)
        Debug.Assert(False)
        GetMailItemSenderAddress = ""
    End Function

You don't need the MailItem to do this..

Here is some sample code that I have

VB Code:

Dim myOlExp As Explorer
  Dim myOlSel As Selection
  Dim myOlMail As MailItem
  Dim i As Integer, j As Long
  Set myOlExp = ActiveExplorer
  Set myOlSel = myOlExp.Selection
  For j = 1 To myOlSel.Count
    Set myOlMail = myOlSel.Item(j)
    MsgBox myOlMail.Subject
    MsgBox myOlMail.Sender
    Set myOlMail = Nothing
  Next j
  Set myOlSel = Nothing
  Set myOlExp = Nothing

It picks up the selected email and get's both the subject and the sender

Hey Danny,

On the line: myOlExp = ActiveExplorer
It says ActiveExplorer is not declared. The other three variables I've added 'Outlook.' in front of them and they seem to be fine. How can I fix that line?

VB Code:

Dim myOlApp As Outlook.Application
  Dim myOlExp As Outlook.Explorers
  Dim obSi As Outlook.Selection
  Dim obMi As Outlook.MailItem
  Set myOlApp = GetObject(,"Outlook.Application")
  Set myOlExp = myOlApp.Explorers
  Set obSi = myOlExp.Item(1).Selection
  For i = 1 To obSi.Count
    Set obMi = obSi.Item(i)
    Debug.Print obMi.SenderName
    Debug.Print obMi.Subject
  Next i
  Set obMi = Nothing
  Set obSi = Nothing
  Set myOlExp = Nothing
  Set myOlApp = Nothing

Try that one

What do I declare obMi, obSi, obEx and obOt as?

Sorry.. Copy and paste error.. will fix it in the original

It works! :)
Thanks! :thumb:

I have a few more questions though. Where can I look for documentations on other fields? Specifically the body of the email, date, etc.?
When I first access that code, there's a pop up that asks if I'm going to allow the program to access my email. Is it possible to get rid of that somehow? May be not by code but through registry?

Another question, which is an entirely different topic, how persistent are class variables? I have a public class variable in my form that I would like to be accessible in other classes such as Connect, through out the instance of Outlook. How can I achieve that?

Because you have declared obMi As Outlook.MailItem you can scroll through the remainder of a mail item's properties by pressing .

The pop up message is outlook security Perform a search for ClickYes, this is program that will continue to scan for messages like this and click's the yes button for you. There are other methods which does include changing the registry.

To allow a variable to be available throughout your whole project declare it as a global variable in module (or Public if you prefer)

Since I'm creating an add-in, would the global variable be in the Connect class? I tried to declare the global variable in the form but I suppose the value of the variable is re-initialized everytime the form is loaded.

How can I declare the variable in Connect and be able to use it in the form as well? It wouldn't let me do Connect.globalvar. I've also tried defining an object for connect then go objConnect.globalvar and that crashes.

But you are using the MailItem.

VB Code:

Dim obMi As Outlook.MailItem

That's Just Picking on me :D

In fact you don't need the mail item.. it is easier with it though..

VB Code:

Dim myOlApp As Outlook.Application
  Dim myOlExp As Outlook.Explorers
  Dim obSi As Outlook.Selection
  Set myOlApp = GetObject(,"Outlook.Application")
  Set myOlExp = myOlApp.Explorers
  Set obSi = myOlExp.Item(1).Selection
  For i = 1 To obSi.Count
    Debug.Print obSi.Item(i).SenderName
    Debug.Print obSi.Item(i).Subject
  Next i
  Set obSi = Nothing
  Set myOlExp = Nothing
  Set myOlApp = Nothing

hey guys...referring to my post , what should I do about global variable?

Danny, your code was working fine but I don't know what's wrong now.

VB Code:

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
        Dim myOlApp As Outlook.Application
        Dim myOlExp As Outlook.Explorers
        Dim obSi As Outlook.Selection
        Dim obMi As Outlook.MailItem
        Dim i As Integer
 
        MsgBox("1")
 
        myOlApp = GetObject(, "Outlook.Application")
 
        MsgBox("2")
 
        myOlExp = myOlApp.Explorers
 
        MsgBox("3")
 
        obSi = myOlExp.Item(1).Selection
        MsgBox("about if")
        If obSi.Count > 0 Then
            MsgBox("in if")
            For i = 1 To obSi.Count
                obMi = obSi.Item(i)
                MsgBox(obMi.SenderName)
                MsgBox(obMi.Body)
            Next i
            obMi = Nothing
            obSi = Nothing
            myOlExp = Nothing
            myOlApp = Nothing
        Else
            MsgBox("in else")
            MsgBox("Please select an email.")
        End If
 
 
        Me.Close()
    End Sub

It crashes after msgbox 1 pops up. Any idea?

This is actually inside Outlook? or some other office app?

It's used in Outlook, developed in Visual Studio.

Ok the code is actually from Access...

The line that is causing the problem is the attempt to GetObject if outlook is not open then this will cause a problem.

If the code is inside Outlook you should be able to drop the outlook part of it... like so

VB Code:

Dim myOlExp As Explorers
  Dim obSi As Selection
  Dim obMi As MailItem
  Set myOlExp = Application.Explorers
  Set obSi = myOlExp.Item(1).Selection
  For i = 1 To obSi.Count
    Set obMi = obSi.Item(i)
    Debug.Print obMi.SenderName
    Debug.Print obMi.Subject
  Next i
  Set obMi = Nothing
  Set obSi = Nothing
  Set myOlExp = Nothing

In my corporation VBA is disabled behind Outlook so I cannot test to see if this will actually work

The code wouldn't be used if Outlook is not opened though. I just kept getting the follow msg when it crashes:

Object reference not set to an instance of an object.

Also when I tried the code you provided above, I'm not sure what to set Application as....

You do not need to set Application to anything.. It refers to the Application to which the code resides..

Looking back over your code you are using .Net to build this.. in testing it will attempt to GetObject of Outlook..

If Outlook is not open then it will fail.. you will need to CreateObject instead.

VB Code:

myOlApp = CreateObject("Outlook.Application")

plui31, you are writting this in .NET. Which version and it appears to be automating Outlook and not actually in VBA.
Your attaching your variable object to the .NET Application object and not Outlooks?

Missed that one Danny ;)

I'm testing it by opening up Outlook manually then click on the button I've added. Should I have CreateObject anyway?

I'm using Microsoft Visual Studio .NET 2003.

I'm not sure what you're asking here :confused:

In VB.NET there is an Application object and also in Outlook. Since there was code like this...

VB Code:

Set myOlExp = Application.Explorers

VB doesnt know which your referring to. Now however your current code is , it needs to make the distinction between the two by using the myOlApp object variable being set to the Outlook.Application instance.

aah okay. thanks :) It's working now.

I have a question about the body of the Outlook message. How is a newline represented? I want to replace every newline with a special character. How can I do that?

The new line character is ...
vbNewLine
Chr(13) & Chr(10)
vbCrLf

You can replace a new line with your own character by using the Replace function.

VB Code:

strBody = Replace(strBody, vbNewLine, "NL") 'Or ??? character instead of "NL"

hey RobDog

I've tired the following:

VB Code:

iBody = Replace(iBody, vbNewLine, "%0a")
                iBody = Replace(iBody, Chr(13) & Chr(10), "%0a")
                iBody = Replace(iBody, vbCrLf, "%0a")

And I also have this: Replace(iBody, " ", "%20")

I sent myself an email that looks like this:

first line

second line


And after the replace, it merges the string into first%20linesecond%20line.
What's the problem?

Nothing. Your taking out the newlines so you end up with a string with your substitute char as the line breaks but since its not a line break it wont break. ;)

True...but how come my substitute character, "%0a", isn't there?

What char does "%0a" represent? I know its supposed to be a web thing, right?

Yeah, it's suppose to be a newline for forms and %20 is a space. Any idea how to get it to work?

What is the version of Outlook and what is the .BodyFormat of the email?

It's Outlook 2000.
I'm not sure what .BodyFormat is...

This is weird. I changed my code to:
iBody = Replace(iBody, vbNewLine, "xxx")

and it was fine. It got it right. But when it's "%0a", It just merges together...

Will the newline work if its not in a form?

.BodyFormat is only available in Outlook 2002+

You may want to use the .HTMLBody to display your body text in HTML. Your special chars should work correctly in that format.

I think as long as it's a textbox then it should work.

What U talk'n bot willis? ;)

The .HTMLBody is available in Outlook 2000.

Here is the specifics on the HTMLBody property in Outlook 2000.

mis-read.. though he was talking about .bodyformat :D

aaah alright. I'll look into it.

Thanks for all your help, Danny & RobDog! :)
